In the case of the connection method shown in FIG. 3, the elastic clip 32 is elastically fitted so as to straddle the supply pipe 20 and the pipe end 22 through the fitting opening 36, and a pair of flanges 24 that are overlapped with each other are formed. The supply pipe 20 and the pipe end 22 are connected by engaging with the engagement clip 40 of the elastic clip 32.
[0026]
As shown in FIG. 1, the faucet 10 of the present example includes a downward spout 42 at the front portion of the case 14.
Reference numeral 44 denotes a faucet operation unit.
[0027]
In FIG. 1, reference numeral 46 denotes a back plate, which is elastic packing such as a rubber packing which is preliminarily formed into a predetermined shape along the outer peripheral portion of the back surface, specifically, along the upper side portion and the left and right side portions, and has a shape retaining ability. 48 is attached.
The back plate 46 is fixed to the wall surface 49 by screws 52 as fixing means in the fixing holes 50 in a state where the elastic packing 48 is brought into contact with a vertical mounting surface, in this example, the wall surface 49 (see FIG. 2). It has come to be.
[0028]
The back plate 46 is formed with an upright wall 54 that rises in a direction away from the wall surface 49 along the upper side portion and the left and right side portions, and further has a hook-like fitting ridge that extends outward at the tip portion. 56 is formed continuously along the upper side and the left and right sides.
The back plate 46 is fixed to the wall surface 49 with its lower end substantially in contact with the floor surface 21.
[0029]
The fitting protrusion 56 is integrally formed with a locking protrusion 58 that protrudes to the left and right sides at an intermediate portion in the vertical direction. The locking projection 58 is for temporarily supporting the case 14 at a position lifted from the floor surface 21 by a certain distance, as will be described in detail later.
[0030]
The case 14 has a shape in which a rear surface and a lower surface are opened, and an inward fitting corresponding to the fitting protrusion 56 on the back plate 46 side along the upper side and the left and right sides of the rear side. The joint groove 62 is formed continuously. The fitting groove 62 has an open lower end.
[0031]
Also in the fitting groove 62, a locking recess 64 having a shape corresponding to the locking protrusion 58 on the back plate 46 side is formed at an intermediate portion in the vertical direction.
The locking recess 64 is formed at a position for engaging the locking protrusion 58 in the final assembled state. The locking recess 64 cooperates with the locking protrusion 58 to prevent the case 14 from coming out upward.
[0032]
A seal member 65 that abuts against the floor surface 21 and performs a sealing action is attached to the lower end surface of the case 14 along the outer periphery of the lower surface. However, the seal member 65 can be omitted.
[0033]
In the faucet mounting structure of this example, first, the back plate 46 is fixed to the wall surface 49 on the floor surface 21 with screws 52. At this time, the elastic packing 48 attached in advance along the outer peripheral portion of the back plate 46 is brought into contact with the wall surface 49, and the elastic packing 48 seals the gap between the back plate 46 and the wall surface 49 in a watertight manner. can do.
[0034]
Therefore, even when splash water from the spout 42 or moisture in the bathroom flows down the wall surface 49, the flowing water is prevented from entering the inside of the case 14 through the mounting holes 50 of the back plate 46. .
[0035]
Now, after fixing the back plate 46 to the wall surface 49 in this way, the case 14 is then assembled to the back plate 46 with the faucet body 12 accommodated therein.
[0036]
The assembly is simply performed by fitting the lower end opening of the fitting groove 62 formed in the rear peripheral portion of the case 14 to the fitting protrusion 56 of the back plate 46 and sliding the case 14 downward in that state. It can be done easily.
[0037]
At that time, it is necessary to connect the lower end portion of the supply pipe 20 and the pipe end portion 22 protruding from the floor surface 21. At that time, if the case 14 is suddenly slid downward to the final assembly position, that is, the position where the lower end of the case 14 comes into contact with the floor 21, the connection work between the supply pipe 20 and the pipe end 22 cannot be performed. .
Therefore, when connecting the supply pipe 20 and the pipe end 22, it is necessary to temporarily hold the case 14 at a position raised from the floor surface 21 by a certain distance.
[0038]
Here, in the faucet mounting structure of this example, as shown in FIG. 4, the locking projection 58 provided on the back plate 46 is hooked on the lower end of the case 14, and the case 14 is temporarily temporarily supported. Therefore, it is possible to connect the supply pipe 20 and the pipe end 22 while holding the case 14 in a state of being lifted from the floor surface 21 by a certain distance.
[0039]
Thus, when the case 14 is pushed downward further after the connection work is completed, the locking projection 58 is engaged in the locking recess 64 on the case 14 side at the final assembly position, where the case 14 is The back plate 46 is prevented from coming off (upwardly coming off).
[0040]
In the case of the faucet attachment structure of this example, the case 14 is attached to the wall surface 49 via the back plate 46, and further, the gap between the back plate 46 and the wall surface 49 is sealed in a watertight manner by the elastic packing 48. Therefore, even when splash water from the water discharge port 42 or, for example, moisture in the bathroom flows down through the wall surface 49, the flowing water is well prevented from entering the case 14.
[0041]
In addition, since the back plate 46 and the case 14 are also watertightly sealed based on the fitting action of the fitting protrusion 56 and the fitting groove 62, the case is formed between the back plate 46 and the case 14. Intrusion of water into the inside 14 is also well prevented.
[0042]
Accordingly, the infiltration of water into the case 14 solves problems such as dirt accumulated in the case 14 or the dirt eventually oozes out from the case 14 and impairs the beauty around the faucet. be able to.
[0043]
Further, according to the faucet mounting structure of this example, since it is not necessary to perform caulking between the case 14 and the wall surface 49 to perform sealing, the faucet 10 can be easily maintained with the case 14 attached and detached. Moreover, the fall of the aesthetics around the faucet attachment part resulting from the caulking can be avoided.
[0044]
Although the embodiment of the present invention has been described in detail above, this is only an embodiment.
For example, in the above example, the fitting protrusion 56 is formed on the back plate 46 side and the fitting groove 62 is formed on the case 14 side. On the contrary, the fitting groove is formed on the back plate 46 side. It is also possible to provide a fitting protrusion on the case 14 side.
[0045]
Further, in that case, a locking projection 58 for temporarily supporting the case 14 temporarily on the case 14 side and a locking recess 64 on the back plate 46 side can be formed. The invention can be configured in various forms without departing from the spirit of the invention.
